River in Virginia, United States

The navigable portion of the river was the major highway of colonial Virginia during its first 15 years, facilitating supply ships delivering supplies and more emigrants from England. However, for the first five years, despite hopes of discovering gold ores, these ships sent little of monetary value back to the sponsors. In 1612, businessman John Rolfe successfully cultivated a non native strain of tobacco which proved popular in England. Soon, the river became the primary means of exporting the large hogsheads of this cash crop from an ever growing number of plantations with wharfs along its banks. This development made the proprietary efforts of the Virginia Company of London successful financially, spurring even more development, investments and immigration. Below the falls at Richmond, many James River plantations had their own wharves, and additional ports and/or early railheads were located at Warwick, Bermuda Hundred, City Point, Claremont, Scotland, and Smithfield, and, during the 17th century, the capital of the colony at Jamestown. Navigation of the James River played an important role in early Virginia commerce and in the settlement of the interior, although growth of the colony was primarily in the Tidewater region during the first 75 years. The upper reaches of the river above the head of navigation at the fall line were explored by fur trading parties sent out by Abraham Wood during the late 17th century. Although ocean going ships were unable to navigate beyond present day Richmond, portage of products and navigation with smaller craft to transport crops other than tobacco was feasible. Produce from the Piedmont and Great Valley regions descended the river to seaports at Richmond and Manchester through such port towns as Lynchburg, Scottsville, Columbia and Buchanan.

The James River was considered a route for transport of produce from the Ohio Valley. The James River and Kanawha Canal was built for this purpose, to provide a navigable portion of the Kanawha River, a tributary of the Ohio River. For the most mountainous section between the two points, the James River and Kanawha Turnpike was built to provide a portage link for wagons and stagecoaches. However, before the canal could be fully completed, in the mid 19th century, railroads emerged as a more practical technology and eclipsed canals for economical transportation, ending the canal's progress at Eagle Rock. The Chesapeake and Ohio Railway (C&O) was completed between Richmond and the Ohio River at the new city of Huntington, West Virginia by 1873, dooming the canal's economic prospects. In the late 19th century, the Richmond and Alleghany Railroad was laid along the eastern portion of the canal's towpath, and became part of the C&O within 10 years. In modern times, this rail line is used primarily in transporting West Virginia coal to export coal piers at Newport News.

During the 1960s and 1970s, mishandling and dumping of the insecticide Kepone resulted in the contamination of large stretches of the James River estuary downstream of the Allied Signal Company and LifeSciences Product Company plants in Hopewell, Virginia. Because of the pollution, sections of the river were considered "dead" and unfit for human use, and many businesses and restaurants along the river suffered economic losses. In December 1975 Virginia Governor Mills Godwin Jr. shut down the James River to fishing for 100 miles, from Richmond to the Chesapeake Bay. This ban remained in effect for 13 years, until efforts to clean up the river began to show results. A decade of accumulated silt, lying above the contaminated riverbed, helped to reduce levels of the chemical.

Since the 1970s, the health of the James River has improved substantially. The Chesapeake Bay Agreement of 1983, signed by the governors of Maryland, Virginia, and Pennsylvania, the mayor of the District of Columbia, and the EPA, established baseline environmental protections and promoted regional cooperation conducive to river clean up. This original agreement has evolved as the Chesapeake Bay Program. The James River Association (JRA), founded in 1976, began publishing State of the James reports in 2016. In their 2023 report, JRA concluded that the "overall grade of the State of the James has improved to a B with a score of 66% from its failing health decades ago."

The James River drains a catchment comprising 10432 square miles (27,019 km2). The watershed includes about 4% open water and an area with a population of 2.5 million people (2000). The James River forms near Iron Gate on the border between Alleghany and Botetourt counties, from the confluence of the Cowpasture and Jackson rivers in the Appalachian Mountains. It flows into the Chesapeake Bay at Hampton Roads. Tidal waters extend west to Richmond at the river's fall line (the head of navigation). Larger tributaries draining to the tidal portion include the Appomattox River, Chickahominy River, Warwick River, Pagan River, and the Nansemond River. At its mouth near Newport News Point, the Elizabeth River and the Nansemond River join the James River to form the harbor area known as Hampton Roads. Between the tip of the Virginia Peninsula near Old Point Comfort and the Willoughby Spit area of Norfolk in South Hampton Roads, a channel leads from Hampton Roads into the southern portion of the Chesapeake Bay and out to the Atlantic Ocean a few miles further east. Many boats pass through this river to import and export Virginia products.

The James River contains many parks and other recreational attractions. Canoeing, fishing, kayaking, hiking, and swimming are some of the activities that people enjoy along the river during the summer. From the river's start in the Blue Ridge mountains to Richmond, numerous rapids and pools offer fishing and whitewater rafting. The most intense whitewater stretch is a 2 mile (3 km) segment that ends in downtown Richmond where the river goes over the fall line. This is the only place in the country where extensive class III (class IV with above average river levels) whitewater conditions exist within sight of skyscrapers. Below the fall line east of Richmond, the river is better suited for water skiing and other large boat recreation. Here the river is known for its blue catfish, reaching average sizes of , with frequent catches exceeding In the Chesapeake watershed, the James River is the last confirmed holdout for the nearly extirpated Atlantic sturgeon. In May 2007 a survey identified 175 sturgeon remaining in the entire river, with 15 specimens exceeding 5 feet (2 m).

The Monitor Merrimac Memorial Bridge Tunnel prohibits bicycles, but bicyclists may take the Jamestown Ferry. After a fatal accident on the Boulevard Bridge , the City of Richmond requires bicycles to travel on the sidewalk for the length of the bridge.

The James River Reserve Fleet is the anchorage for a large portion of the National Defense Reserve Fleet, called the "James River fleet" or the "ghost fleet", consisting of "mothballed" ships, mostly merchant vessels, that can be activated within 20 to 120 days to provide shipping for the United States during national emergencies, either military or non military, such as commercial shipping crises. The fleet is managed by the U. S. Department of Transportation's Maritime Administration and is based in Fort Eustis, Virginia. It is a different entity from the United States Navy reserve fleets, which consist largely of warships.
